In an increasingly urbanized world, construction industry is called upon to serve the needs of human society, such as environmental protection and safety in terms of infrastructure. In this context, a sustainable and ethical development means a close connection between buildings and environment. This connection can be achieved through, for example, the concept of ecological concrete or green concrete, as it is often called. The conventional process of obtaining cement and mineral aggregates from the concrete composition generates pollution, especially through (...) greenhouse gas emissions. Also, one should not ignore the fact that extraction of the raw materials affects the habitats of the sites and of the neighboring areas. When construction materials are questioned, the ethical issues lay not in the means of expression, but mainly in the means of production. More to the point, the present contribution aimed to find solutions for enhancing the adhesion of vegetal aggregates with the cement matrix, in order to obtain a material with optimal mechanical properties, which is valued as an ethical approach of building industry. Results showed that plant aggregates can be used to obtain a building material which can be improved by using partial substitution of cement by silica fume, fly ash, or by using additives and that green concrete as an environmentally friendly material offers the alternative for lower energy use and fewer CO2 emissions. Marketers must understand not only the advantages of these green materials, but also that they have an ethical commitment to provide consumers with environmentally friendly materials. (shrink)

His philosophical thinking was influenced by his legal knowledge, but when reading carefully his articles and papers we can notice a detachment from the philosophical premises in the development of the concepts of law. Like Del Vecchio, Djuvara makes no difference between law and philosophy and therefore the legal philosophy looks like a completion of law, these two concepts being comprehended only by a general, epistemological and philosophical approach; the issues related to the philosophy of law are not only isolated (...) from the big philosophical issues but there are closely related to them so that the philosophy of lawintegrates completely in the general philosophy.

The lost celebration. To live the sacred, that means to admit its presence in the world and to celebrate this presence; respectively, to affirm the presence of its absolute value, of the Meaning, finally, in the horizon of harmony and joy, and to fill up ourselves by that. In nowadays, do we really know to live the feast, namely the feast of our spirit? Do we still have the wish and the wisdom to institute sacred times and spaces, to offer (...) our soul to the joy and not to the manipulation, to the ritual and not to the rut-ness? Are we able to escape from the tyranny of clamor and of instinct? These are questions to which we are trying to find some answers in our essay. (shrink)
